WIZ550S2E Programmer's Guide
Overview
This page provides detailed information about AT commands set and how to use the Configuration
tool, which retrieves and sets all configurations of WIZ550S2E via Ethernet. Users can change any
value of the WIZ550S2E and communicate with the peer system through TCP(or UDP) socket by
sending AT commands.

WIZ550S2E AT Command Set
This section provides a list of WIZ550S2E AT commands and their functions. Users can input
commands and parameters through USART line. Every command starts with “AT”. Any other initial
character will cause an error in return. Commands and parameters are all ASCII characters, i.e. when
you input 'AT+NSTAT', you should input ASCII characters 'A', 'T', '+', 'N', 'S', 'T', 'A', 'T' and 'Enter Key'
which is CR, LF (0x0d, 0x0A).
All commands should be terminated with
CR(0x0D), LF(0x0A)
Some parameters are mandatory and others are optional. Parameters must be entered in the order of
format column given by the command tables. Although the optional parameter is not used, the
comma delimiters ',' must still be included in the command. In most cases, valid commands return the
character [S] and invalid inputs return [F]. The possible responses sent from WIZ550S2E to the user
are described as Responses. Below are examples of user input. As you can see, WIZ550S2E return
“\r\n” back instead of “\r”, which means user (host system) always handle '\r\n' as the only delimiter.
Input by User AT\r\n (0x61 0x74 0x0d 0x0a)
Output from WIZ550S2E [S]\r\n (0x5b 0x53 0x5d 0x0d 0x0a)

most OS platforms including Windows, MAC OS and Linux. Please download .jar file and execute it
over Java Virtual Machine.
There are two options on how to run the configuration tool.
Run the jar file from the GUI environment.1.
The jar file cannot be opened if the jar file is perceived as a compressed file. In this case, modify1.
the setting of the compression software and do not open the jar file in compressed file method.
In case of Linux or Mac, the following must be given permission.2.
chmod 0755 WIZ550S2E_Configuration_Tool.jar1.
Enter the following command in the terminal to run the program.2.
java -jar WIZ550S2E_Configuration_Tool.jar1.
WIZ550S2E Configuration tool consists four sections

Common Configurations
Search
The Search function is used to search for all existing WIZnet's WIZ550 series modules on the same
LAN. By using UDP broadcast, it finds all modules on the same subnet, and found devices will be listed
in the “Serial to Ethernet” tree(Search Window) with its MAC address.
Setting
This function is used to apply your configurations.
When you select the MAC address from the “Search Window”, the default value of the module will be
displayed. Modify your configurations and click “Setting” button to apply your settings. The module
will re-initialize and save the changed configurations.
Users can change the configurations by the following steps.

1. Select the MAC address of the device which you would like to modify in
the
“Search Window”
2. Modify the settings according to your needs
3. Click the “Setting” button and then "Password Input Windows" pop up
- Default Password is "WIZnet"
4. Input "Setting Password" and Click "OK" button
5. The module will be initialized by a re-booting process
6. To verify your settings, please click ‘Search’ button and view your new
settings
F/W Uploading
Firmware will be uploaded through TFTP. Click “F/W Uploading” Button and a popup window will
shows as follow.
Server IP : TFTP Server IP
Server Port : TFTP Server Port (TFTP default Port : 69)
File Name : Firmware File Name
Password : Setting Password
☞ WIZ550S2E Configure tool is not supported TFTP server. So you use TFTP program separately.

IP
This section is for setting WIZ550S2E mode's network information
IP:
WIZ550S2E's IP Address
Gateway:
WIZ550S2E's Gateway Address
Subnet mask:
WIZ550S2E's Subnet Mask
Host IP:
Peer system's IP address which WIZ550S2E connects(or sends) to,
when its operating mode is "TCP Client","TCP Mixed" or "UDP".
☞ If you are unclear about your Local IP, Subnet Mask, Gateway information, you have to get this
information from your network administrator. If the IP address is not correct, IP collision or network
problems may occur.
Port
This section is for setting WIZ550S2E's Port information.
Local port :
WIZ550S2E's local port number
Remote port :
Peer system socket's port number which WIZ550S2E connects(or sends) to ,
when its operating mode is "TCP Client","TCP Mixed" or "UDP".
Working Mode
The working mode of WIZ550S2E can be divided into TCP Server, TCP Client and TCP Mixed according
to the connection establishing method, but UDP processes the data communication without
connection establishment.
During TCP server mode, WIZ550S2E operates as the server and waits for the connection trial from
the client. WIZ550S2E operates as the client in TCP Client mode and tries to connect to the server’s IP
and Port. Mixed mode supports both Server and Client. The communication process of each mode is
as below.
TCP server mode communication
During the TCP Server mode, WIZ550S2E waits for the connection request. TCP Server mode can be
useful when the monitoring center attempts to connect to the device, while WIZ550S2E is installed, in
